As many know, laser sights can be very beneficial; but there is one major flaw... ordinary red lasers can be next to impossible to see in most daylight conditions. The benefit of a green laser is that it is much more visible, allowing for it to be used anytime, day or night, indoors or outdoors, permitting you to track your target quicker and more accurately. Additionally, because green lasers are so much more visible to the human eye, you can actually see a very intimidating visible beam in low-light conditions.

The Difference is Clear

During the Day
Which is more visible to you? On the left we see a traditional red laser sight, compared to the green Viridian in broad daylight. The lasers were at a distance of 25 feet from the wall.

At Night
On the left you can see how visible the beam can actually get during dark or dimmer conditions.

Overcast, In the woods
Shown to the left is an additional day shot, which again shows the dramatic difference.

Why Green Lasers are More Visible

Green is closer to the center of the visible spectrum, at 532 Nanometers, so it's easier for our eyes to perceive the color vs. a red laser at 635 Nanometers. In fact, a green laser can appear as much as 50 times brighter than the red equivalent and as can be seen from the below charts 532 nm is the ideal wavelength to maximize visibility during day or night.

In Daytime Conditions the human eye has maximum sensitivity
at the 555 nm wavelength

In Nighttime Conditions the human eye has maximum sensitivity
of 512 nm wavelength
